Right in front of Chu Yi's eyes, when he saw everything around him clearly, he almost stared out of his sockets.

"This, this...; …;”

Right in front of Chu Yi's eyes, this open underground place, it was not a square space as Chu Yi expected.

It's a complete tunnel in a ring.

And in this width is about hundreds of meters. In the tunnel-like space with an oval shape of hundreds of meters high, Chu Yi even saw that above this tunnel, there was a lush cypress tree growing upside down!

Chu Yi thought he was dazzled, but after rubbing his eyes vigorously, Chu Yi found that all this was true!

A cypress tree grows in the ice overhead. And it grows incomparably stronger against the trend.

Not only that, but after a stream went around this tunnel for almost a circle, a cold pool formed on the tunnel-like wall on Chu Yi's right side.

And whether it's a stream or a cold pool, it's almost like a cold pool on the wall. There is no trace of spillage!

As if, gravity does not work at all here!

Just when Chu Yi was shocked, Lilith spoke.

"Chu Yi. I know you're shocked. ”

"But don't say it's you, even when I first came here, I was taken aback. ”

"Here, it's as if the earth has no gravitational pull. ”

"You can, feel it...; …;”

Chu Yi took a cautious step in disbelief, but this step made Chu Yi feel a different feeling!

It's like floating in space without gravity!

"This?!"

Chu Yi felt that the geographical knowledge he had studied for so many years was completely inexplicable here!

However, this is clearly on Earth!

How is it possible that there is not the slightest gravitational pull around?!

The next moment, Chu Yi took a deep breath and finally walked in completely.

In an instant, Chu Yi felt that his body began to float involuntarily.

Although Chu Yi has never been to space. But it's like swimming in the ocean, where it's no longer air, it's sea!

The next moment, Chu Yi clenched his fists, and the frost qi around him immediately enveloped him.

Then, with the effect of frost qi, Chu Yi swam freely in this space that did not conform to the geomorphological characteristics of any place on the earth.

He first came to the sky above his head, and after controlling the frost qi to turn upside down and step on the ice that was obviously the top, he didn't feel the slightest discomfort.

He glanced at Lilith, who was standing as if she was standing above her head, and immediately began to stride along the circular wall that was as smooth as a tunnel.

After walking around, Chu Yi finally calmed down gradually.

It's time to come. Chu Yi finally believed it, this is really an incredible place!

Even, Chu Yi racked his brains, and he couldn't explain everything that happened here.

Finally, Chu Yi couldn't help but speak to Nangong Yu in his mind.

"Nangong, you must have been here, can you still remember this place?"

Chu Yi wanted to get an answer from Nangong Yu.

But Nangong Yu quickly replied, "I, I vaguely seem to have an impression. ”

"However, I can't quite remember...; …;”

Hearing Nangong Yu's words, Chu Yi shook his head.

Although he didn't know why this place became like this, Chu Yi still looked at Lilith.

"Where's the Ice Palace Underground?"

Lilith raised her hand and pointed to the front of the tunnel.

Chu Yi looked in the direction of Lilith's finger, and immediately saw that at the end of this tunnel, there was an ice wall, and in the middle of this ice wall, there was an ice gate with a diameter of several meters.

Apparently. The underground ice palace is there!

Then, as Lilith walked towards the end with Chu Yi, passing by Hantan, Lilith pointed to it.

"This is the cold spring that our Frost Clan uses to reproduce. ”

After Chu Yi glanced at it, he immediately felt the surging aura inside.

Obviously, after thousands of years of condensation, the aura in this cold spring has been concentrated to a terrifying level!

If you can really get the aura of this cold spring, you will definitely be able to improve Chu Yi's strength.

Of course, Chu Yi knew what this cold spring meant to the Frost Clan, and he couldn't possibly have any thoughts about this cold spring.

Moreover, the current Chu Yi has not yet obtained the Ground Rank Mind Method, and he is not able to continue cultivating at all...; …;

Finally, when Chu Yi followed Lilith to the front of this ice wall, the energy in Lilith's body surged. Immediately push open the circular frost door several meters in diameter.

It was pitch black as ink, and I couldn't see my fingers when I reached out.

The next moment, when Chu Yi tried to reach out into it, he suddenly felt a restraint from his soul appear.

But this restraint from the soul disappeared in an instant after touching Chu Yi's soul, as if there was something similar to it in Chu Yi's body!

Chu Yi is also very clear about this thing. It must be the part of the soul that belongs to Nangong Yu!

For a while, Chu Yi was even a little happy.

At the beginning, because of a mistake, Nangong Yu's soul and his own soul were partially fused.

Although this led to Nangong Yu and Chu Yi being tied together from then on, their strength and soul coexisted.

However, the benefits brought to Chu Yi are countless!

Even, now Chu Yi has been vaguely aware of it.

This Nangong Yu is really not ordinary!

She's definitely not going to be an ordinary person!

Because, for now, she has experienced what happened thousands of years ago, and what she has done has exceeded Chu Yi's understanding!

Even said that there was no restraint just now.

If it weren't for Chu Yi's soul, part of Nangong Yu's soul was integrated. I'm afraid that soul bondage will not be able to pass through him no matter what.

Taking a deep breath and calming down, Chu Yi finally looked back at Lilith.

"Then I'm in...; …;”

However, before Chu Yi finished speaking, he suddenly saw Lilith's eyes widen in surprise.

"Y-You can get in!"

Kindness?!

Chu Yi was stunned for a moment, and after reacting. He immediately looked at Lilith in disbelief.

"Could it be that for thousands of years, the people of your Frost Clan have never entered it?!"

Lilith nodded hurriedly, "That's right, no one has been in for thousands of years. ”

"Everything, it's because of that layer of shackles from the soul that no matter how much we improve our strength, we can't break through that shackles!"

As soon as the conversation turned, Lilith's face was full of excitement and relief.

"But now it's okay, you can go in!"

"Besides, now you still want to say that you are not a Xuannu envoy?"

"This is something that can only be entered with the soul breath of the Xuannu Lord!"

Chu Yi was silent this time.

He could finally be sure.

Nangong Yu must be the existence that was called a Xuannu by the Frost Clan thousands of years ago!

In an instant, Chu Yi was suddenly extremely curious about the former Nangong Yu.

What a terrible existence can create all this in front of you?!

However, Chu Yi also knew that Nangong Yu's memory was almost completely lost now, and it was impossible to tell him.

The next moment, Chu Yi clenched his fists.

It seems that everything can only be discovered by yourself!

Finally, Chu Yi looked back at Lilith.

"You wait for me here, I'll go back as soon as I go. ”

After speaking, Chu Yi took a deep breath and plunged headlong into this ink-black unknown.

Seeing this scene, Lilith's excited heart beat faster.

"It's been a thousand years!"

"Someone can finally unlock the secret that our clan has guarded for thousands of years!"

…; …;

At the same time, when Chu Yi finally entered this dark world.

Suddenly, everything around me brightened a little.

Then, while Chu Yi was still floating in the air, an illusory figure with an unclear face suddenly appeared in front of him.

Kindness?!

Chu Yi immediately became vigilant, his eyes firmly fixed on the figure that was gradually approaching him.

However, at this moment, a sound came from this figure that made Chu Yi almost stare his eyeballs out of his sockets.

"You're still here...; …;”

This voice...; …;

Chu Yi's heart almost jumped out of his throat.

How is this sound possible?!

Actually, it's Nangong Yu?!
